Feature description

Knowing your domain may help hackers and other attackers when they trying to use brute force and break into your website by guessing passwords. For that reason the WordPress + Office 365 Login can be configured to redirect anyone who enters a user name ending with your (custom or default cloud) domain e.g. john.doe@your-domain.(onmicrosoft.)com into the default WordPress login form to Microsoft instead. Of course this is not a bullet proof solution but it will surely help avoid so called brute force attacks from being successful.
